摘要
A color chart for color selection includes a plurality of color patches including first to third color patches arranged satisfying at least one of the following conditions (a) and (b). (a) An absolute value of a lightness difference between the first color patch and the second color patch in a first scale that is perceptually more uniform than lightness in the CIE L*a*b* color system and an absolute value of a lightness difference between the second color patch and the third color patch in the first scale are identical. (b) An absolute value of a chroma difference between the first color patch and the second color patch in a second scale that is perceptually more uniform than chroma in the CIE L*a*b* color system and an absolute value of a chroma difference between the second color patch and the third color patch in the second scale are identical.
